It carries a 24 V DC coil with integral suppression, meaning the flyback diode is built in — no external snubber needed on the coil drive. Rated for utilisation categories AC-1, AC-3, AC-3e, and AC-4, the 12 A AC-3 rating at ≤ 440 V is the one that governs motor switching duty — that is the current it can make and break across a typical induction motor load. For resistive loads (AC-1), electrical durability is 0.3 Mcycles at 20 A.
This contactor carries approvals across IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and EN 45545 (R22 HL3) for rail vehicle fire safety. Safety reliability is quantified: B10d = 1,369,863 cycles at nominal load per EN/ISO 13849-1, and 20,000,000 cycles with mechanical load only — useful data for safety circuit design where the contactor is part of the stopping chain. Flame retardance is V0 per UL 94.
The spread is clean — no broker hunt required, no last-time-buy window to watch. If your BOM calls this order code, it ships from the regular supply channel.
Mounts on rail or plate. Power circuit connections use ring lugs (7 mm outer diameter) with a tightening torque of 0.8 to 1.3 N·m. The auxiliary contact is a single NC instantaneous type. Coil operating time: 10 to 20 ms for de-energisation and NO opening, 30 to 40 ms for energisation and NO closing. Minimum switching capability is 5 mA at 17 V for signalling circuits — important when the auxiliary contact drives a PLC input with low wetting current. Heat dissipation is 1.8 W at 20 °C, both inrush and hold-in.
